Researchers from Seville (Spain) recently used a validated questionnaire to determine the frequency with which 316 female cyclists from an association took nutritional supplements, the type of supplement and the reasons for taking them.
Results published in the journal Nutritional values found that 85.1% of the female racing cyclists surveyed used SS.
The main reason given for taking dietary supplements was “health status”, the second most common reason being “athletic performance”.
“These results provide the first evidence of SS use among female road cyclists and highlight certain patterns that need to be considered,” the authors concluded.
Nutritional supplements for cyclists
Cycling is a physically demanding sport with significant aerobic demands. SS can play a crucial role in training and competition planning and is mainly used to improve energy availability, performance, training support and micronutrient management.
SS consumption is widespread among athletes and increases among elite athletes compared to lower-level athletes in the same sport. However, SS consumption is higher among men than among women in the same category, level and sport.
The number of federation licenses in women’s cycling in Spain has increased recently. However, the authors of the current study noted: “Despite progress in gender equality and the increasing participation of women in various sports, there is a notable lack of scientific studies aimed at establishing specific nutritional recommendations for female athletes and other physically active women.”
Racing cyclists
The authors contacted clubs and associations registered with the Andalusian Cycling Federation (FAC) by email.
The survey asked for information on the types of dietary supplements taken, reasons for taking them, sources of advice, places of purchase, times of consumption and perception of the results achieved.
SS were categorised according to the groups and subgroups defined by the Australian Sports Institute (AIS, 2023) based on the level of evidence supporting their use.
The analysis found that 85.1% of female racing cyclists surveyed used SS, with an average intake of seven supplements per person.
The most commonly consumed supplements were sports bars (77.5%), sports gels (61.4%) and caffeine (49.1%). Other important supplements were mixed macronutrient supplements (26.3%), beta-alanine (10.4%), sodium bicarbonate (8.2%) and creatine (5.7%).
The main reasons for taking SS were health status (78.2%), athletic performance (67.9%) and nutritional deficiencies (47.5%).
Participants reported that the most important advisors for dietary supplements were nutritionists (58.9%), physicians (44.6%), and fitness coaches (36.4%). According to the results, amateur athletes were less likely to seek professional advice.
The main sources of supply were pharmacies (60.8%) and specialty stores (59.2%). However, the researchers also found that a relatively high proportion of online purchases (44.9%) pose a risk for unintentional doping due to possible contamination and lack of regulation.
The authors found that underuse of scientifically validated supplements highlighted a gap in optimal SS use.
“Given the low intake of many supplements in the performance supplement subgroup, such as beta-alanine, sodium bicarbonate, creatine, dietary nitrate/beetroot juice, and glycerin, it is important to educate athletes about their potential benefits,” the authors concluded.
“In addition, it is recommended that their specific ergogenic effects be investigated through randomized controlled trials in the context of women’s road cycling.”
